I came across a few pictures from other rennlisters doing some suspension work....

I am TRYING to install my new coilovers suspension but I CANT get the big suspension bolt out.

I got both nuts loose but even using a 5lbs sledge.... I cant get the suspension bolt to budge.

Unless I am missing something if I keep slamming the bolt I am pretty much going to destroy it.

Any help really appreciated .

Keep the rear most nut and washer on there, and use that as a pry/rotation point. If it will turn freely, it will come out with a bit of prying as you rotate.

When it comes out far enough to slip a large wrench behind the washer, use it and a dead blow hammer and pound it out.

Well, first off you want to drive the shaft to the rear. Check the clearance towards the front.

So get the front nut off and then use a pickle fork or crow bar to lever the then out. Dig in behind the large washer.

You might not be getting it off with the sledge since the whole mess is mounted in rubber bushings. That takes up the shock. Can you get it to twist? These have a tendency to rust in place. The long rod goes through metal tubes inside the bushings. If those rust together you'll have to cut the rod to get the thing apart.

Thank you for the replys. I had to call it a night before I started destroying stuff

I cant even get the suspension bolt to twist..... I tried locking 2 nuts together trick but that did not work.

I am quite familiar with 911's but have never worked on a 928. So the suspension bolt comes out towards the rear of the car?

I like the pickle fork idea.... that will be my attack tool tomorrow

so theres no hidden lock pins or anything like that?

thanks again

Nope..should pull right out.

Herman with a bit of patience you may get the pin out without destroying it.
But first you need to spray the whole part of the linkage with PB or Kroil .

The other trick is to spray the pin from the bottom.

There are 2 holes in the hub carrier and the pin is visible from those holes so you can spray the pin and hopefully the oil will loosen the corrosion.
it would be best to let this assembly soak overnight.
Follow the advice as others have posted,
once it breaks loose you may have to work it back and forth while spraying from the bottom of the Hub carrier .
It might also be wise to order another pin a used one will work just roll it on a flat surface first to check that it is not bent.
Use a generous amount of anti seize on the pin when you install it, use thick grease to hold in the beveled washers

Yeah... They don't always pull right out (although they are supposed to). Sometimes they can be nearly impossible to remove due to corrosion, and the solution can require cutting the pin. However, in your case, the suspension looks pretty clean, so I would think you should have a reasonable chance of pulling it out without damage.

Thats the odd thing.

They fell right out of my Ohio car...

Do what Stan suggests and spray from beneath through the holes.

Then undo one end, stick an impact gun on the other end's nut and use it to spin the rod. Then put that end back on and do the same for the other end (it may seem redundant - but spinning both ways will help flake off any corrosion thats binding against the steel washers in the hub carrier).

Then put a sacrificial nut on the front end and beat on that with a hammer to move the pin out rearwards. If it stops moving, put a nut on the other end and beat it back to where you started, then spray more from beneath to lube the newly exposed bits beneath the corrosion, before beating it aft again.

Not that I ever want this problem...but man I deserve to go all out "Thor" on something on a car for once...a lifetime of "son of a..." owes me this.

Also try hot/boiling water as well as penetrating oil, maybe with a bit of vinegar in it. The water will try and dissolve the corrosion oil won't.

I guess I am not very lucky, because most that we do seem to have at least one of the pins stuck .
we use spacers and then the not as a puller.
beating on the threads will only cause problems .

put pressure on with the nut then tap and try to turn and try turn the pin.

Is the picture with the red shocks from the car in question? If so, you can be almostvsure it didn't corrode solid to the shock, which it normally does. Or are these shocks put on without anti-seize? On my car I had to cut the pin on one side of the shock. On a set I bought from a salvage yard I had to cut it on both sides of the shock because it was rock solid in both the shock and the arm.

Oh Boy!
That does remind me something...
Don't worry, they will eventually come out. One way or an other...
I had this exact same problem about 2 months ago and finally had to remove the hub from there and use a 20T press and a lot of heat cycle to take those f... out! They were really stuck there.
I hope yours will come out without to mutch trouble.
A lot of Rennlisters have took them out without mutch trouble.
But salt and aluminium don't give anything good.
My PO told me that my car was never driven durring winter. BS!
Maybe not him, but the one before him for sure...

If you are ready to sacrifice your actual shocks, this is how I did it.

Good luck and let us know how things will go.
Were are you in Canada?

If your car is the one in the pic as well as the above you may also want to release the sway bar.
